Simple ions include Na +, Ca 2+, and Cl –. Polyatomic ions include (NH 4) +, (CO 3) 2-, and OH –. Unlike protons and neutrons, electrons can be easily removed and added to an atom. Ions are formed as a result of this addition or removal of electrons from the atom. Negative ions, known as anions, form when an atom gains electrons and now has ...
